Is My Mattress Alive? [VIDEO]

This weekend, I decided it was time to clean out my guest bedroom closet. Things got kind of gnarly in there. While I was sitting on the floor putting my clothes on hangers, I rested my back on the bed. I felt something move behind me. I looked on top of the bed - no kids, dogs, or cat. I looked under the bed - no kids, dogs, or cat. But, I kept feeling a strange feeling. Here's what I found. It scared the crap out of me.

Oh and don't judge me for the garage floor dust on the baby mattress at the bottom. It happens, yall. It happens.
